Good to see your enthusiasm but i would advise you to first do a solo ride to some easy hill station and fathom the power of your scooty and your stamina.Scooty can surely go to Ladakh...many people have taken scooty but you need to first learn the basics of solo two wheeler riding and a short ride will prepare you for Ladakh-and Spiti.

Nothing is impossible if you are determined enough. Good to see your confidence over your riding skills as well. But I would suggest you to first go to other places of Himachal and then you would get more confidence on your riding and then you can plan for Spiti/ Leh or any other destination like these it's always said that " Never stop a free bird as it's useless" they would fly limitless.

Well!! It does sound really alluring and so even we want to do it but it isn't a cake walk! I have seen and know people covering this (even Ladakh) through Kinetic Honda and even Bajaj chetak (scooter) and It involves hell a lot of exercise! I am in no way trying to kill your aspiration and I am sure you ride well but it’s good to ponder all the pros n cons. Riding in hills is altogether different from riding in a city. The blind turns, the precipitous slopes, the high climbs n hails n what not.! You must have a basic know how about your vehicle if something goes wrong! at least how to fix a puncture n stuff. desk-bound straight (90 degree) on one place, riding for hours, keeping conscious while driving is all unquestionably a mission. You ride for few hours n realize the bums going numb and back starts hurting n all sorts of things.! It is undeniably a tremendously blissful experience but it is treacherous too. I suggest to begin with, you try the Delhi - Ladakh bus service .. it is safer as compared to bike ride and if you find yourself up and running (because that journey is also a task) when you return.. then think of living your dream. All the best.
